Setup
- Stand tall with feet hip-width apart and hands in a 'guard' position near your chin.
- Shift your weight onto one leg, keeping a slight bend in the knee, and lift the opposite foot slightly off the ground.
- Engage your core and fix your gaze on a point at eye level to assist with balance.
How to do it
- While maintaining balance on the standing leg, throw a cross punch with the opposite arm, rotating your torso across your midline.
- Exhale forcefully on the punch and inhale as you snap the hand back to the starting guard position.
- Alternate punches between the left and right arms while remaining balanced on the same standing leg for the duration of the set.
- Perform the movement with a controlled, rhythmic tempo, ensuring the standing leg remains stable.
Form checklist
- Keep the standing knee slightly flexed (soft) to engage the quadriceps and glutes.
- Ensure the rotation comes from your midsection rather than just swinging the arm.
- Keep your hips as stable as possible, resisting the urge to tip over during the reach.
- Maintain a proud chest and neutral spine, avoiding any rounding of the upper back.
Pro tips
- Imagine 'wringing out' your torso like a towel to maximize oblique engagement during the cross-body reach.
- Focus on a quick retraction of the punch to challenge your balance through rapid deceleration.
- Grip the floor with your toes to increase proprioception and stability in the standing ankle.
Make it harder
- Perform the exercise on an unstable surface like a foam balance pad or BOSU ball.
- Hold light dumbbells or wear weighted gloves to increase the demand on the deltoids and core stabilizers.
